A precision method has been developed to determine atomic binding energies by means of magnetic analysis of photo electrons expelled from thin evaporated layers by x radiation. The accuracy achieved in the present investigation is of the order of one electron volt, the limits being set essentially by the inherent widths of the atomic levels. The element Cu has been studied and the K and L/sub I/ binding energies found are 8985.5 ev and 1100 ev respectively. Further, the KLL and KLM Auger spectra have been in vestigated. Seven well-resolved lines have been obtained in the KLL group. Earlier investigations have given only three KLL Auger lines in Cu due to insufficient resolution, whereas theory indicates the possibility of ten lines in this group. Peaks due to electrons which have suffered discrete energy losses are observed on the low energy flanks of the photo lines. (auth)
